A little more specs would help. Like the Motherboard and maybe PSU. As far as this list goes, that CPU needs a good upgrade would be to the FX 4130, which is about 90 dollars. And if you are looking for a good CPU and your not on a budget, I would recommend a Intel, the i5 4670k. If you are on budget a good GPU for you would be 250X or 260X or a 750ti. If you are only looking for a good GPU go with the R9 270X/280X or GTX 760/770.
You should get a new SSD/Harddrive, and I don't see the 8 Gigs of RAM being a problem, so I guess thats it.
